Comparison of geometrical and acoustical characteristics of human supraglottal spaces for ordinary and singing voice using finite element models

Original language description

The contribution deals with the design of the volume and subsequently finite element (FE) models of the human vocal tract for phonation of the vowel /a:/ without and with the singer?s formant. The models were developed from the MR measurements. The MR investigation of acoustic vocal spaces was performed for two male singers singing vowel /a:/ with and without the singer?s formant. The result show substantial increase of the volume and length of the vocal tract and changes in the acoustic frequency-modalcharacteristics of the FE models of the acoustic spaces due to the existence of the singer?s formant.
